The provisions of this chapter shall apply to existing buildings containing ambulatory care facilities in addition to the requirements of Chapter 11 of the International Fire Code. Where the provisions of this chapter conflict with either the construction requirements in Chapter 11 of the International Fire Code or the construction requirements that applied at the time of construction, the most restrictive provision shall apply.
The intent of this appendix is to provide a minimum degree of fire and life safety to persons occupying and existing buildings containing ambulatory care facilities where such buildings do not comply with the minimum requirements of the International Building Code.
Ambulatory care facilities where the potential exists for four or more care recipients to be incapable of self-preservation at any time, whether rendered incapable by staff or staff has accepted responsibility for a care recipient already incapable, shall be separated from adjacent spaces, corridors or tenants with a fire partition installed in accordance with Section 708 of the International Building Code.
Where the aggregate area of one or more ambulatory care facilities is greater than 10,000 square feet (929 m2) on one story, the story shall be provided with a smoke barrier to subdivide the story into no fewer than two smoke compartments. The area of any one such smoke compartment shall be not greater than 22,500 square feet (2092 m2). The travel distance from any point in a smoke compartment to a smoke barrier door shall be not greater than 200 feet (60 960 mm). The smoke barrier shall be installed in accordance with Section 709 of the International Building Code with the exception that smoke barriers shall be continuous from an outside wall to an outside wall, a floor to a floor, or from a smoke barrier to a smoke barrier or a combination thereof.
Not less than 30 net square feet (2.8 m2) for each nonambulatory care recipient shall be provided within the aggregate area of corridors, care recipient rooms, treatment rooms, lounge or dining areas and other low-hazard areas within each smoke compartment. Each occupant of an ambulatory care facility shall be provided with access to a refuge area without passing through or utilizing adjacent tenant spaces.
A means of egress shall be provided from each smoke compartment created by smoke barriers without having to return through the smoke compartment from which means of egress originated.
An automatic sprinkler system shall be provided throughout the entire floor containing an ambulatory care facility in Type IIB, IIIB and VB construction where either of the following conditions exist at any time:
1.Four or more care recipients are incapable of self-preservation, whether rendered incapable by staff or staff has accepted responsibility for care recipients already incapable.
2.One or more care recipients that are incapable of self-preservation are located at other than the level of exit discharge serving such a facility.
In buildings where ambulatory care is provided on levels other than the level of exit discharge, an automatic sprinkler system shall be installed throughout the entire floor where such care is provided and all floors below, and all floors between the level of ambulatory care and the nearest level of exit discharge, including the level of exit discharge.
Fire areas containing ambulatory care facilities shall be provided with an electronically supervised automatic smoke detection system installed within the ambulatory care facility and in public use areas outside of tenant spaces, including public corridors and elevator lobbies.
Exception: Buildings equipped throughout with an automatic sprinkler system in accordance with Section 903.3.1.1 of the International Fire Code, provided the occupant notification appliances will activate throughout the notification zones upon sprinkler waterflow.
Incidental uses associated with and located within existing ambulatory care facilities required to be separated by Section 422 in the International Building Code, and that generally pose a greater level of risk to such occupancies, shall comply with the provisions of Sections K103.2 through K18.104.22.168. Incidental uses in ambulatory care facilities required to be separated by Section 422 of the International Building Code are limited to those listed in Table K103.1.
INCIDENTAL USES IN EXISTING AMBULATORY CARE FACILITIES
|ROOM OR AREA||SEPARATION AND/OR PROTECTION|
|Furnace room where any piece of equipment is over 400,000 Btu per hour input||1 hour or provide automatic sprinkler system|
|Rooms with boilers where the largest piece of equipment is over 15 psi and 10 horsepower||1 hour or provide automatic sprinkler system|
|Refrigerant machinery room||1 hour or provide automatic sprinkler system|
|Hydrogen fuel gas rooms, not classified as Group H||1 hour in ambulatory care facilities|
|Incinerator rooms||2 hours and provide automatic sprinkler system|
|Laboratories not classified as Group H||1 hour or provide automatic sprinkler system|

|Stationary storage battery systems having a liquid electrolyte capacity of more than 50 gal-lons for flooded lead-acid, nickel cadmium or VRLA, or more than 1,000 pounds for lithium-ion and lithium metal polymer used for facility standby power, emergency power or uninterruptible power supplies||1 hour in ambulatory care facilities|
For SI: 1 square foot = 0.0929 m2, 1 pound per square inch (psi) = 6.9 kPa, 1 British thermal unit (Btu) per hour = 0.293 watts,1 horsepower = 746 watts, 1 gallon = 3.785 L.
Incidental uses shall not be individually classified in accordance with Section 302.1 of the International Building Code. Incidental uses shall be included in the building occupancies in which they are located.
Incidental uses shall not occupy more than 10 percent of the building area of the story in which they are located.
The incidental uses listed in Table K103.1 shall be separated from the remainder of the building or equipped with an automatic sprinkler system, or both, in accordance with the provisions of that table.
Where Table K103.1 specifies a fire-resistance-rated separation, the incidental uses shall be separated from the remainder of the building in accordance with Section 509.4.1 of the International Building Code.
Where Table K103.1 permits an automatic sprinkler system without a fire-resistance-rated separation, the incidental uses shall be separated from the remainder of the building by construction capable of resisting the passage of smoke in accordance with Section 509.4.2 of the International Building Code.
Except as otherwise specified in Table K103.1 for certain incidental uses, where an automatic sprinkler system is provided in accordance with Table K103.1, only the space occupied by the incidental use need be equipped with such a system.
The minimum width of each door opening shall be sufficient for the occupant load thereof and shall provide a clear width of not less than 28 inches (711 mm). Where this section requires a minimum clear width of 28 inches (711 mm) and a door opening includes two door leaves without a mullion, one leaf shall provide a clear opening width of 28 inches (711 mm). In ambulatory care facilities, doors serving as means of egress from patient treatment rooms shall provide a clear width of not less than 32 inches (813 mm). The maximum width of a swinging door leaf shall be 48 inches (1219 mm) nominal. The height of doors openings shall be not less than 80 inches (2032 mm).
1.Door openings to storage closets less than 10 square feet (0.93 m2) in area shall not be limited by the minimum width.
